Issue your invoice online free of charge and download it as a PDF
Fill in the fields, look at the finished invoice and download it, free of charge and without registration. It is a full-fledged invoice including your logo, stamp and signature. Nothing is stored anywhere: the invoice is created, you download it, and that is the end of it.
This is for you if…
… you invoice occasionally and do not need a program for it. Typically a sole trader or a small company that is not a VAT payer and issues a few invoices a month. An invoice with VAT can be issued here too: the rates and the tax recapitulation are on it.
This is not for you if…
… you already have to send electronic invoices, or you need payment tracking and records you can rely on without having to look after your own file.
It fills the book with fifteen finished invoices in two number series for three customers, so that you can try everything at once: pick a customer with one click, open an invoice, correct it, duplicate it, delete it and download it. It overwrites what you have in the form and in the book. Your remembered details are not lost, they come back when you reload the page.
Invoice book
The page keeps issued invoices in a single file that you download to your computer. When you load it next time, you will see all your invoices here: you can open any of them, correct it, print it again or make the next one from it. The number of a new invoice is filled in by the page itself. The file never reaches our server and we know nothing about it, so it is up to you where you keep it and how often you back it up.
The book holds invoices that are not in the downloaded file yet. Before you close the page, download the invoice book again and overwrite the old file with it.
Close it with Esc or by clicking next to the invoice. If the invoice does not appear, use the Download PDF button.
The invoice book is not downloaded
You are leaving the page and the book holds invoices that are not in any file yet. The page does not remember the book, so you will lose these invoices by leaving.

Renumber the following invoices?
Deleting left an empty place in the number series. The following invoices can be moved one lower so that the series has no gap. An invoice you have already sent to the customer will change only in the book – the original number stays on their copy.

This is not an electronic invoice. It is an invoice on paper: a PDF that you send by e-mail or print. No machine file is created from it and nothing is sent anywhere, so it will not fulfil your obligation to send e-invoices. Our matu.sk application is there for that.
What happens to your data
The invoice is not stored anywhere
The data you fill in goes to the server, which draws the PDF from it and sends it back. Neither the invoice, nor your logo, nor the customer name stays there. When you close or reload the page, the unfinished invoice is gone on your side too. Issued invoices can be kept in your own file, which stays on your computer.
Your company details stay with you
So that you do not retype them for every invoice, your browser remembers them, on your computer, not with us. The Forget my company details button clears them.
Company details from public registers
When you press Fetch from register, we send the name or IČO you typed to public registers (the register of legal entities, the register of financial statements and the EU VAT register). We do not store or record any of it. If you prefer not to, type the details in by hand and nothing goes to any register.
The invoice looks like it came from an accountant
It is drawn by the same part of the program as our application for clients. It is not a simplified one-off form, but a complete invoice with everything that belongs on it.
FAQ
Frequently asked questions about issuing an invoice
Is it really free?
Yes, with no registration and no limit on the number of invoices. The page only has an hourly cap on invoices rendered from one connection, so it cannot be abused to flood the server. Occasional invoicing will never reach it.
Does this fulfil my duty to issue an electronic invoice?
No. An electronic invoice is a machine file that is sent into the network and the customer's accounting system reads it by itself. If you need an invoice like that, take a look at our application, which can do it including the sending.
I am not VAT registered. What should I fill in?
Turn off the VAT registered switch and leave the VAT ID field empty. The invoice will then show no rate and no tax summary, only the amount due.
Why is there no payment QR code on the invoice?
It appears on its own once you enter a valid IBAN and the amount due is positive. It is a Pay by square code, as used by Slovak banks: the customer scans it in their banking app and the payment is pre-filled.
Can I correct an invoice and issue it again?
As long as the page stays open, yes: change what you need and click Show invoice again. Once you close or reload the page, the invoice data is gone; only your company details stay. If you keep an invoice book, you can open any invoice in it even half a year later and correct it under the same number.
I need invoice numbering, records and payment tracking. Can I do that here?
Partly yes: the invoice book below the form keeps a list of issued invoices and the number series, but all of it lives in your own file and only if you download it. You will not find payments, stock or e-invoice sending here, that is what our matu.sk app is for. If you invoice regularly, write to us and we will keep your whole accounting.
Don't want to issue invoices yourself?
Write us how many invoices you issue per month. We will get back to you with a price and take care of them together with your accounting. With no obligation and no pressure.
